Design And Realization Of Intelligent Skipping Rope Measuring System

Now has been around as a test of sports examinations.However,most of the current skipping test also uses manual counting,not only the existence of counting error,and because each candidate needs a person for its count,the examination is less efficient.Now,some schools use to automatically count the wireless rope skipping device,but from the use of point of view,there are still wireless transmission near,small network size,high cost shortcomings.In view of the problems existing in these intelligent jumpers,we study and design the intelligent rope skipping evaluation system,Communication technology,increase the wireless transmission distance and network size,to achieve 50 people in the case of no manual test at the same time,the real examination of the automation.First of all briefly introduces the current situation and the significance of jump rope at home and abroad."Rope skipping automatic counter" device has been developed,to a certain extent,to solve the previous rope skipping count "depending on the number of mouth" state.However,from the use of the situation,there are still wireless transmission near the network size is small,the high cost of shortcomings,research and development for students in the usual test exercises and in the test rope skipping test to promote the realization of skipping test automation,with broad application prospects.According to the actual demand of the intelligent rope skipping evaluation system.Respectively,the demand for intelligent skipping device description,functional description,performance requirements given specific requirements.Simultaneously analyzes the basic structure of the intelligent rope skipping device,and then puts forward the design of the intelligent rope skipping evaluation system according to the concrete requirement of the student examination.The intelligent skipping device has two different modes of operation: stand-alone work and networking work.At the same time built-in Hall sensor,infinite communication module,segment screen LCD,power module.According to the basic structure of intelligent rope skipping machine to complete the functional modules of the hardware design process and software design process.First of all,the intelligent winder master chip selection,and then respectively,the segment screen LCD display module,Hall sensor module,WI-FI module,power and buzzer module hardware selection and design,through the design of each module Completed the hardware skipping device hardware design.The software module includes the main program design module,the system initialization module,the segment screen LCD display design module,the Hall sensor module and the WI-FI module.Laboratory testing of intelligent rope skipping.Test results show that the intelligent rope skipping module hardware design is reasonable,the software system is stable,accurate calculation of skipping number,the function to meet the design requirements,can be used in skipping test.
